Ling flood
Ling flood, commonly known as ice, is a common phenomenon of ice in the river, is the ice on the water flow resistance caused by the river water level rose significantly hydrological phenomenon. Ice can sometimes gather into ice plugs or ice dams, causing a substantial elevation of the water level, the final floodplain or burst, known as Ling Hong. In the winter of the closure of the river and the open period of spring are likely to occur in the flood season. Yellow River Ningxia section of the total length of 397 kilometers, generally since mid-December each year began to flow Ling Ling, the following year in early January closure of the river, Affected by special natural and geographical conditions, the Yellow River Ningxia section of the closure of the river from north to south, the first downstream of the upstream, when the river from south to north, the first upstream and downstream, almost every year the occurrence of different levels of flood disaster. In layman's terms, there is ice in the water meter, and the rupture into a block, ice under the water, driving the ice to the downstream movement, when the embankment is frozen when the ice accumulation, resulting in the dam pressure is too large, that is, China's northern rivers, such as the Yellow River, Heilongjiang, Songhua River, prone to ice floods. ...
